Haven't been on this site much lately but I thought I let people know that after 3 years, I've found my Holy Grail that made a night & day difference in my audio sound for CD's without changing my speaker system at all. Based on things I read online, I purchased a Musical Fidelity X-10 V3 Tube Buffer that I got new from the online company Music Direct, here's the link http://www.musicdirect.com/products/...sku=AMUFIX10V3 for $330 including shipping at a discount from the $399 plus shipping retail price. Somehow & I don't know how or why, it absolutely totally changed my audio sound magically to a night & day improvement. Music on CD now sounds like performances not recordings as if the group is playing right in front of me. Instruments have shifted places, there's more clarity especially in the seperation of instruments & vocals, the sound is deeper, fuller, more detailed, crisper & I know longer have to increase the volume to get an increase in dynamics. I've tried tube CD players before, various other $500-$1500 CD players, various DAcs by themselves & all of them sounded worse then my existing system- this thing changes mine completely. You can also somehow use this on 2 front speakers for home theater sound while still getting the 5.1 sound, I don't quite understand how & am not about to spend my time figuring out how now. The way this works is you simply connect the analog outs on your CD player by cable to the X-10 V3 analog ins & then connect the analog outs on it to your receiver. You need 4 cables, they should be the exact same ones not a mixture. While my Pioneer PD-59 CD player has an excellent transport & I love its digital sound when I use an optical cable to my Denon 3801 Receiver, quite frankly its internal DAC sucks & produced mediocore at best analog sound. But when I connect the X-10 V3 to it, the analog sound is amazing. I'm hoping to eventually upgrade & get a good external DAC (possibly Musical Fidelitys X-10) which should further improve the X-10 V3 sound as well as Cables, probably Signal Cable Silver Resolution & a further Musical Fidelity power upgrade which they said would also improve sound. Anyway, I'd advise anyone who's interested to check it out at Music Direct, they have a 30 day return policy.
